I was driving with my friend today in his 98 z28 Camaro. It has longtube headers and other basic mods. The A/c is disconnected ( belt blew off, haven't had the time to fix that yet. ) While driving in LA we hit a bump on the road instantly smoke started coming in the cab , through the A/C vents . Smelt like burnt oil. I told him to shut it off asap we did , I then opened the hood and say seam/ smoke coming from the divers side header area, but could not tell where it was coming from. So I told him to drive to the nearest parking lot so we were not in the road . Parked the car the smoke was gone has not come back drove about another 10 miles on it still no issues
My idea is " the longtube header hit and opened up the header gasket for a few seconds and then closed , since his camaro is lowered.
I am no camaro expert by any means . Ideas would be greatly appreciated.
FYI did the normal checked for leaks drips lost of oil or coolant nothing not even a drop..
